Which type of vitamin is soluble in water but not in fat, and is generally not stored in the body?

Water-soluble vitamins are characterized by their solubility in water, which distinguishes them from fat-soluble vitamins that dissolve in fats and oils. This unique property means that water-soluble vitamins, such as the B-complex vitamins and vitamin C, are readily absorbed into the bloodstream and are not stored in significant amounts in body tissues. Instead, they must be consumed regularly through diet because any excess is excreted in urine rather than being stored for future use. This is essential for maintaining appropriate levels in the body, as deficiencies can occur quickly without regular intake.

Additionally, the storage and transport characteristics of water-soluble vitamins emphasize their critical role in various metabolic functions, including energy production and promoting the health of skin, eyes, and nervous system. Understanding this classification aids in making informed dietary choices to ensure adequate intake of these vitamins.
